Combination of liquid lithium with Reduced Activation Feritic/Martensitic Steel (RAFM) is one of the options for Test Blanket Module (TBM) in early ITER period and early DEMO blanket, as well as an intermediate step toward Li/V DEMO blanket. In this paper, characterization of a Li/RAFM blanket was carried out and comp…
Limitations in operating conditions, primarily the steady-state operating temperature, of silicon carbide-based ceramics and composites for applications to structural and functional components in fusion blanket systems were critically examined based on the latest experimental results. Irradiation-induced high temperat…
Presently, chemical seed treatments are in discussion due to their directly or indirectly impacts on human health or other living organisms. They may also negatively affect the ecosystem and the food chain. In rice seeds, chemicals may cause phytotoxic effects including seed degradation. Eugenol is the main component…
In the present experiment, the dielectric response of various types of epoxies was investigated in the frequency and time domain. The samples consisted of nanostructured epoxy microcomposites and reference microcomposites. Water ingression at the fabrication step and/or at measuring time is known to affect the dielect…
Magnetic nano-particles of cobalt ferrite were prepared using co-precipitation method. X-ray diffraction, transmission electron microscope and Raman analysis have confirmed that the formation of cobalt ferrite nano-particles with different particle size depending on the rate of reaction and nucleation. X-ray photoelec…
Abstract Summary: Nanocomposites of ultra‐high molecular weight polyethylene (UHMWPE) filled with multi‐walled carbon nanotubes (CNT) were obtained by in situ polymerization of ethylene by TpTiCl 2 Et. This novel catalytic complex activated with polymethylaluminoxane (P‐MAO) (Al:Ti = 200) allowed to incorporate the CN…
The problem of using discharge and noise characteristics of primary cells with the lithium-thionyl chloride system is examined in order to monitor the state of these power sources (primarily their depth of discharge). An analysis of special features of the discharge curves for lithium-thionyl chloride cells of the bob…
The electrochemical characteristics of composite cathodes made of (La, Sr) MnO3-(Zr, Sc)O2 (LSM-SSZ), modified with PrO2 − x additive, and designed for application in solid oxide fuel cells at moderately high temperatures were studied. The relationship between activity of catalytically modified composite LSM-SSZ catho…
Ashcraft-type samples have been used to grow vented water trees in crosslinked polyethylene and crosslinked polyethylene based nanocomposites with 5 wt% and 12.5 wt% functionalized silica. Tree growths are reported at a range of stresses by sectioning the samples destructively. A nondestructive method is also introduc…
Here we approximate the plasma kinetics responsible for diamondlike carbon (DLC) depositions that result from pulsed-dc discharges. The DLC films were deposited at room temperature by plasma-enhanced chemical vapor deposition (PECVD) in a methane (CH4) atmosphere at 10 Pa. We compared the plasma characteristics of asy…
This manuscript presents a theoretical analysis of the correlation between the computed bulk modulus and the structure of a series of multicomponent sodium diborate based glasses in terms of the bond compression model. The main parameters in the analysis were the computed elastic moduli, the average stretching force c…
The relationship between space charge accumulation and breakdown at various temperatures is investigated by observing the space charge formation in low density polyethylene (LDPE) and LDPE/MgO nanocomposite material under dc high stress. We have reported, earlier, that, enhancement of electric field in LDPE by packet-…
The energies of the ground 4f n levels of tri- and divalent rare-earth ions with respect to the conduction and valence bands of Gd2O2S crystal has been determined. It is shown that the Pr3+, Tb3+, and Eu3+ ions can be luminescence centers in Gd2O2S. The levels of the Nd3+, Dy3+, Er3+, Tm3+, Sm3+, and Ho3+ ions lie in…
Lead-free piezoelectric ceramics (1−x)K0.5Na0.5NbO3–xAgSbO3+0.75 mol % MnO2 were prepared by a conventional solid-state sintering technique, and the piezoelectric and dielectric properties of the ceramics were studied. The results of x-ray diffraction suggest that AgSbO3 diffuses into the K0.5Na0.5NbO3 lattices to for…
The electrospinning system mainly has vertical type and horizontal type according to the geometrical arrangements of ejecting capillary and collection target, where vertical type includes shaft type and converse type. The fibers were obtained in several kinds of typical electrospinning parameters by using three differ…
We consider the interaction between a particle beam and a propagating electromagnetic wave in the presence of a metamaterial. We show that the introduction of a metamaterial gives rise to a novel dispersion curve which determines a unique wave particle relationship, via the frequency dependence of the metamaterial and…
The dynamics of change in temperature at the edges of a layered structure consisting of one or more electrocaloric and heat-conducting elements in response to pulses of a periodic electric field has been studied with the use of the finite-element method. The possibility of using ceramic materials and (Ba,Sr)TiO 3 film…
The structural and thermodynamic features of the elastic-plastic transition in armco iron and its plastic deformation are studied. Energy storage in iron is shown to have a nonlinear character and be accompanied by wavelike heat dissipation. To describe the energy balance in the plastically deformed metal, a theoretic…
Molecular dynamics simulations were conducted to investigate the interfacial thermal conductance between a functionalized single-wall carbon nanotube and a silicon substrate. Based on Fourier’s law, interfacial thermal conductance of the system with different numbers of chemical bonds was calculated. The results showe…
ZnTiO 3 thin films were prepared by radio frequency cosputtering of ZnO and TiO2. It was found the as-prepared film is amorphous and the cubic phase ZnTiO3 films form after annealing at temperature above 500 °C. The absorption spectra indicate that the optical band gap of the crystalline ZnTiO3 film is about 3.70 eV.…
